UNITEK S1242AGY01 USB4 NVMe M.2 SSD Enclosure 40Gbps 3800MB/s Cooling Fan for Thunderbolt 3/4
Blazing 40Gbps USB4 NVMe Enclosure with Active Cooling – Up to 3800MB/s
The UNITEK S1242AGY01 SolidForce Reefer TurboCool USB-C NVMe M.2 SSD Enclosure turns any NVMe SSD into an ultra‑fast external drive. With USB4 interface (40Gbps) and real‑world read/write speeds up to 3800MB/s, it rivals internal SSDs. The built‑in cooling fan automatically activates above 45°C, ensuring sustained performance during large file transfers, video editing, or gaming.
Ultimate Speed for Professionals and Gamers
40Gbps bandwidth – fully utilises NVMe Gen3 and Gen4 drives (limited by SSD and host)
3800MB/s typical read/write – transfer 100GB in under 30 seconds
Perfect for 4K/8K video editing, high‑res photo processing, game libraries, and data backups
Active Cooling for Stable Performance
Unlike passive enclosures that overheat and throttle, the SolidForce Reefer features:
Temperature‑controlled cooling fan (starts at 45°C)
Silicon thermal pad for heat transfer from SSD to housing
Aluminum alloy housing with heat dissipation holes
This triple‑layer cooling keeps your drive running at full speed even during sustained heavy workloads.
Wide Compatibility – USB4, Thunderbolt, USB 3.2 and More
Works with any USB‑C host that supports NVMe external storage:
USB4 / Thunderbolt 4 / Thunderbolt 3 – full 40Gbps
USB 3.2 Gen 2 (10Gbps), USB 3.2 Gen 1 (5Gbps) – backward compatible
USB 3.1/3.0/2.0 – works at lower speeds
Plug and play – no drivers required. Supports Windows, macOS, Linux, Android, and iOS (on devices that allow external storage).
Supports M.2 NVMe SSDs up to 8TB
Form factors: 2242, 2260, 2280
Key types: M‑Key and B+M Key (PCIe/NVMe only – not compatible with SATA M.2)

Technical Specifications
Frequently Asked Questions
1. What SSDs are compatible with this enclosure? +
It supports M.2 NVMe PCIe SSDs (M‑Key or B+M Key). It does not support SATA M.2 SSDs or mSATA drives. Sizes: 2242, 2260, 2280.
2. What is the maximum speed I can get? +
The enclosure supports up to 40Gbps (4000MB/s theoretical). Real‑world speeds depend on your SSD (e.g., a Gen3 NVMe may deliver ~3500MB/s, Gen4 up to 7000MB/s but enclosure max is 3800MB/s due to USB4 overhead). Typically 3800MB/s read/write.
3. Does the cooling fan run all the time? +
No. The fan activates only when the internal temperature exceeds 45°C, reducing noise when not under heavy load.
4. Is the fan noisy? +
The fan is designed for quiet operation. Under normal use, it may be barely audible. At full load, there is some airflow sound, but less than a typical laptop fan.
